表结构及数据

drop table if exists `locationpoint`;
create table `locationpoint`
(
    `id`        int(11)       not null auto_increment,
    `province`  varchar(20)   not null,
    `city`      varchar(20)   not null,
    `longitude` double(10, 3) not null,
    `latitude`  double(10, 3) not null,
    primary key (`id`)
) engine = innodb
  auto_increment = 1156
  default charset = utf8;

insert into `locationpoint`
values (1, '山东', '济南', 116.938477, 36.597889),
       (2, '河北', '石家庄', 114.477539, 38.030786),
       (3, '浙江', '杭州', 120.058594, 30.334954),
       (4, '河南', '郑州', 113.629, 34.744),
       (5, '安徽省', '合肥', 117.170, 31.520);

查询方式

(以内蒙古自治区呼和浩特市为计算中心)

select id,
       city,
       longitude,
       latitude,
       round(
                   (
                           st_distance(
                                   point(longitude, latitude),
                                   point(111.621094, 40.913513)
                               ) / 0.0111
                       ) * 1000
           )
           as distance
from locationpoint
order by distance;
